[JoshuaKGoldberg]

👋 Hi all! With ESLint v9 released, many community plugins are adding support for the new major version. This is a tracking issue of ESLint v9 compatibility for the ~35 or so most popular plugins for ESLint that already support flat config. We'll keep this list updated over time.

If the plugin you're looking for isn't in this list, check 📈 Tracking: Flat Config support. This list treats flat config support as a prerequisite for full ESLint 9 support.

[vincentbriglia]

add gund/eslint-plugin-deprecation#79 to the ones that need support and thanks for this list!

[JoshuaKGoldberg]

@vincentbriglia eslint-plugin-deprecation doesn't yet support flat config, so it's relegated to the other list: gund/eslint-plugin-deprecation#85

[pauliesnug]

v9 support was added to eslint-plugin-solid in solidjs-community/eslint-plugin-solid#140, with solidjs-community/eslint-plugin-solid#141 awaiting a peer dependency update

[MikeMcC399]

• eslint-plugin-cypress now supports ESLint 9.x in release v3.2.0 through PR feat: support eslint v9 through @eslint/eslintrc cypress-io/eslint-plugin-cypress#203.

• The README includes instructions for using release v3.2.0 with ESLint v7, v8 and v9.

• Thanks to the ESLint team for support regarding backwards compatibility of the API Docs: context migration suggestions fail on earlier v8 versions eslint.org#559!

• Work is on-going regarding flat config updates.

[julienw]

https://github.com/testing-library/eslint-plugin-testing-library might be a good one to track as well. Here is their bug about the migration: testing-library/eslint-plugin-testing-library#899

[JoshuaKGoldberg]

@julienw that'd be a good one to include, but it doesn't yet support flat config: testing-library/eslint-plugin-testing-library#853. See #18093.

[nzakas]

As a note, we've now introduced a compatibility package for issues related to the ESLint v9 rule API changes.

[yannbertrand]

A few more:

• i18n-json unmaintained for 2 years, issue referencing flat config support,
• chai-expect, issue referencing flat config support
• knex

[jeremymeng]

vscode-eslint extension support: microsoft/vscode-eslint#1644

[Snafuh]

NX support was merged in nrwl/nx#24632. I think there is already an released version with v9 support as well.

[robertIsaac]

NX support was merged in nrwl/nx#24632. I think there is already an released version with v9 support as well.

I'm not sure if they support eslint 9 or not because of nrwl/nx#25938

[a-schyja]

Here is another one that supports flat config:

• eslint-plugin-check-file

[JamesHenry]

angular-eslint v18 supports ESLint v9

[davidjbng]

There is a PR in Tanstack Query to support ESLint v9:

• feat: ESLint v9 Support TanStack/query#7543

[nzakas]

VS Code extension has been updated:
microsoft/vscode-eslint#1644

[michaelfaith]

Now that Flat Config support has been added to eslint-plugin-jsx-a11y, we should be able to track the v9 support here. This is the issue filed for it: jsx-eslint/eslint-plugin-jsx-a11y#978

[MatthijsKok]

Tanstack Query has v9 support TanStack/query#7543

[mdjermanovic]

eslint-plugin-react v7.35.0 supports ESLint v9

[fasttime]

@​types/eslint v9 has been published: https://www.npmjs.com/package/@types/eslint/v/9.6.0

[domengabrovsek]

The link in the list for check-file plugin is broken, it's probably meant to be https://github.com/dukeluo/eslint-plugin-check-file.

[soren121]

eslint-plugin-compat v6.0.0 supports ESLint v9: amilajack/eslint-plugin-compat#627

[karlderkaefer]

could we add airbnb also to the list? airbnb/javascript#2961

[nzakas]

Airbnb is being tracked here: #18093

[julienw]

eslint plugin for testing-library supports flat config as of v6.3 https://github.com/testing-library/eslint-plugin-testing-library/releases/tag/v6.3.0
